I'm almosy afraid to brag, but my psoriasis has been under control for months now. I use a concoction of vasaline and Ponds lotion.
I have used everything I can think of, but it always came back, stronger than ever. All of a sudden, I had a memory of when I was about 7/8 and had Psorisis on my knees. I got into my Mom Old pink Ponds and vasaline....it worked..

That's my story and I'm sticking to it.
